Is burning a marshmallow a chemical change?
It is easier in this case to say why it isn't a physical change. As you cannot turn a roasted marshmallow back into an un-roasted one, A chemical reaction must have occurred. Cooking is normally a chemical change as you cannot un-cook something.
What action will result in product with chemical properties?
A chemical reaction will result in a product with not only chemical properties (which are different than the reactants), but also physical properties (which are also different from the reactants).
How are physical weathering and chemical weathering alike and different?
Physical weathering and chemical weathering both involve the breakdown of rocks, but through different processes. Physical weathering involves the physical breakdown of rocks into smaller pieces without changing their composition, while chemical weathering involves the alteration of rock composition through chemical reactions with substances like water, oxygen, and acids. Both processes contribute to the overall erosion of rocks and landforms over time.
Is air sensitivity a physical or chemical properties?
It is a chemical property as air sensitive compounds react with oxygen or air to yield a different compound. Physical properties don't alter the composition of the compound but rather the behaviour through different molecular arrangement.
Why is taste considered as physical property of matter?
Taste is considered a physical property of matter because it is a characteristic that can be experienced through the interaction of the taste buds on our tongue with molecules in food. Taste is related to the chemical composition of a substance and how it stimulates our taste receptors. Different substances have different tastes based on their physical and chemical properties.
How do you separate matter?
Matter can be separated through physical or chemical means. Physical methods include filtration, distillation, and chromatography, which separate substances based on their physical properties. Chemical methods involve chemical reactions to convert substances into different forms, allowing for isolation of specific components.
Is weathering a physical or chemical change?
Weathering can involve both physical and chemical changes. Physical weathering breaks down rocks into smaller pieces without changing their chemical composition, such as through freezing and thawing. Chemical weathering, on the other hand, alters the chemical makeup of rocks through processes like oxidation or dissolution.
What 2 things can chemical and physical change go through?
Chemical changes involve the formation of new substances with different chemical properties, while physical changes involve alterations in the appearance or state of matter without changing the chemical composition. Chemical changes typically involve the breaking and forming of chemical bonds, resulting in new substances with different properties. Physical changes, on the other hand, involve changes in physical characteristics such as shape, size, phase, or state of matter without altering the chemical composition of the substance.
Does sandstone go through physical or chemical weathering?
Sandstone can undergo both physical and chemical weathering. Physical weathering involves the breakdown of the rock through physical forces such as wind and water erosion. Chemical weathering, on the other hand, involves the alteration of the rock's composition through chemical reactions with elements like water and acids in the environment.
Are compounds created through physical changes?
No, only through chemical reactions. Physical changes never change the chemical makeup of something. For example, water tuning in to ice is a physical change. Ice and water both have the chemical symbol H20. On the other hand, a sodium - water reaction forms Sodium Hydroxide and Hydrogen. The compound, hydroxide, is formed.
How does a physical reaction different form a chemical reaction?
A physical reaction involves changes in the state or appearance of a substance without altering its chemical composition, such as melting, freezing, or dissolving. In contrast, a chemical reaction results in the formation of new substances with different chemical properties through the breaking and forming of bonds, as seen in processes like combustion or rusting. Essentially, physical reactions are reversible while chemical reactions often produce irreversible changes.
Do chemical changes affect the chemical structure of a substance?
Yes, chemical changes result in a change in the chemical structure of a substance. During a chemical change, new substances with different chemical compositions are formed through the rearrangement of atoms and bonds. This is in contrast to physical changes, where the chemical structure remains the same even though the physical properties may change.
